Menus
The Menus softkey displays the hotkey bar for changing to the other measurement
groups. The main measurement menu within each group is directly opened by
pressing the associated hotkey.
d) P/t Normal 8PSK
The P/t Normal 8PSK test settings differ from the P/t Normal GMSK settings (see p. 4.11 ff.) in two
softkeys.
P/t Norm.
8PSK
The P/t Norm. 8PSK measurement control softkey controls the P/t Norm. 8PSK
measurement; see detailed explanation in section Measurement Control on p. 4.10 .
Besides, the measurement control softkey provides hotkeys to define the scope of
the measurement. All these settings are described in more detail in section
Measurement Control (Power Configuration – Control) on page 4.28 ff. The
Repetition, Stop Condition, Display Mode, and Statistic Count softkeys behave as
described in section P/t Normal GMSK on page 4.11 ff. In the P/t Norm. 8PSK
application, there is one additional hotkey:
Ref Power
Mode
The Ref. Power Mode hotkey defines whether the reference power (0-dB line) in
the measurement diagram is derived from the average power of the current
measurement curve
(Current), the average power of the average curve (Average),
or the average power of the current curve with an additional correction for the
deviation due to the data modulated onto the RF signal
(Data Compens.). See
section Measurement Control (Power Configuration – Control) on page 4.28 .

8PSK and GMSK symbol periods are of equal length, see explanation of GSM burst structure at the
beginning of section
Limit lines (Power Configuration – Limit Lines) on page 4.32 .
e) P/t Multislot
The P/t Multislot test settings differ from the P/t Normal GMSK settings (see p. 4.11 ff.) in several
respects. Most of the differences are related to the configuration of the measurement and display
range.
Note: No Free Run trigger must be used in the P/t Multislot, P/Frame, P/Slot Graph, and P/Slot
Table applications.
Multislot
The Multislot measurement control softkey controls the P/t Multislot measurement;
see detailed explanation in section Measurement Control on p. 4.10 . Besides, the
measurement control softkey provides hotkeys to define the scope of the
measurement. Most of these settings are described in more detail in section
Measurement Control (Power Configuration – Control) on page 4.28 ff. The
Repetition, Stop Condition, Display Mode, and Statistic Count softkeys behave as
described in section P/t Normal GMSK on page 4.11 ff. In the P/t Multislot
application, there are two additional hotkeys:
